6 Claims.

It is well known that dentists in preparing gold and other metalfillings for patients often drop pieces of the filling material. As goldis very valuable, every effort should be made to prevent its loss. thatI have devised the apparatus which constitutes the subject matter of thepresent invention.

Generally, the invention comprises a resilient, expansible andcontractible body frame, on each side of which is a slideway, in each ofwhich slideways a resilient, expansible and contractible bow member istelescopically mounted.

To this frame a bib or apron is attached, the arrangement being suchthat with the frame in place, adjusted to fit the body at the waist, andwith the bow members extended, the bib or apron forms a bag or pouchwhich may be collapsed, when not needed, by pressure against the bowmember in a direction normal to the body of the person wearing theapparatus.

Another object of the invention is to provide an apron-bag supportwhich, while holding itself in place on a body by resilient clampingaction, can be adjusted for use by persons of different waist measures.

Other objects will in part be obvious and in part be pointed outhereinafter.

To the attainment of the aforesaid objects and ends the invention stillfurther resides in the novel details of construction, combination andarrangement of. parts, all of which will be first fully described in thefollowing detailed description, and then be particularly pointed out inthe appended claims, reference being had to the accompanying drawing, inwhich- Fig. 1 is a side elevation of my invention, showing its relationto a wearer.

Fig. 2 is an enlarged top plan view of the frame which comprises theessence of my invention.

Fig. 3 is a detail elevation of a portion thereof,

looking in the direction of the arrow a in Fig. 2,

Fig. 4 is a view similar to Fig, 3, looking in the direction of thearrow b in Fig. 2.

Fig. 5 is an enlarged detail side elevation, the bow member being inpart broken away.

Fig. 6 is an enlarged cross section on the line 66 of Fig. 2.

Fig. '7 is a View similar to Fig. 6 of a modification.

In the drawing, in which like numbers of reference indicate like partsin all the figures, it will be seen that the supported frame is composedof two members I and 2 of fiat spring metal, each having its frontportions overlapped and It is with this particular object in viewprovided with slots 5 and II respectively (Figs. 55

3 and 4) Their other ends are bent back upon themselves, as at 3, andthen divergently rearwardly, as at 4.

The front end of the frame member 2 carries a T-stud whose head 'I ispassed through the end enlargement 6 of slot 5 and whose shank 8 worksin slot 5 (Fig. 3).

The front end of the frame member I has a threaded stud 9 that is passedthrough slot II and carries a milled clamping nut I 0 (Fig. 4). By thisarrangement the frame I, 2 can be made larger or smaller according tothe girth of the wearer.

To the outer sides of the frame members I and 2, secured by welding, asat I3, or in any other suitable way, are tubes I2 having longitudinalslots I4 and having their rear ends welded, or otherwise secured, to theends of the extensions 4.

Telescopically mounted in the tubes I2 are rods I5 carrying stop screwsI6 that cooperate with the slot I4 to limit the movements of the rods I5in their tubes I2.

The front ends of the rods I5 have fastened to them the two elements II,I8 of a bow which carries the front of the apron sack I1 The elementsI1, l8 overlap and carry band-embracing elements I9 which are secured tothe free ends of the respective elements I! and I8 and embrace theopposite elements. The bow (formed by I5, II, I8) is not onlytelescopically mounted in the guide tubes I2, but is laterallyextensible and contractable also.

The bow members I1 and I8, as well as the frame members I and 2, arepreferably made of spring metal.

The apron I9 may be provided with a neck loop 28 and a turned-over bagedge I8 fitted over the members I5, I1, I8 (see dotted lines, Fig. 1).

When pressure is applied to the bow I5, I1, I8 in the direction of thearrow 0 in Fig, 1, as when the dentist wearing the apparatus pressesagainst the dental chair, or the patient, while at work, the bow I5,I'I, I8 will be telescoped against the supporting frame (see dottedlines, Fig. 2) and be out of the way.

Instead of round guide tubes I2 and rods I5, other forms, such forinstance as flat guideways I2 and fiat rods I5 may be used if desired.

If desired, a similar outfit can also be Worn by the patient.

From the foregoing description, taken in connection with theaccompanying drawing, it is thought the construction, operation andadvantages of the invention will be clear to those skilled in the art.

What I claim is:

1. A dentists apron holder comprising 2. laterally adjustablebody-embracing frame, and a forwardly extensible bow membertelescopically mounted at the sides of said frame.

2. A dentists apron holder comprising a resilient body-embracing frame,forwardly directed side guideways secured to said frame, rodstelescopically mounted in said guideways, and apron supporting meansconnected to said rods as a bridge.

3. A dentists apron holder comprising a laterally adjustable resilientbody-embracing-frame, forwardly directed ide guideways secured to saidframe, rods telescopically mounted in said guideways, and apronsupporting means connected to said rods as a bridge.

4. A dent-ists apron holder comprising a resilent body-embracing frame,forwardly directed side 'guideways secured to said frame, rodstelescopically mounted in said guidewayaand apron supporting laterallyadjustable means connected to said rods as a bridge.

5. A dentists apron holder comprising a laterally adjustable resilientbody-embra ing frame, forwardly directed side guideways secured to saidframe, rods telescopically mounted in said guideways, and apronsupporting alterally adjustable means connected to said rods as abridge.

6. In dentists aprons, or bibs, a bib, a neck loop for the upper end ofthe bib, the lower extremity of the bib being formed as a pouch, a bodyframe comprising two curved resilient bands to embrace the waist of thewearer, the front portions of said bands being overlapped and slotted,one .of said portions having a headed stud operable in the ,slot of theother portion, and the other portion having a threaded stud with clampnut operating through the slot of the first member for effecting lateraladjustment of the body frame, tubular slotted guideways secured .tosaidbands at the sides, a bow element comprising rods telescopically mountedin said slotted guideways and having pins operating in the slots of saidguideways, a resilient band member secured to the front end of each rod,said last named resilient band members being overlapped, and meansconnecting the overlapping portions of said last named band memberstogether for free self adjustment, said pouch part 10f the apron -01 bibbeing mounted on said bow member,
